1370 the wire. R5 moved close to him, bowed, hrood and tail-wagged, but did not reach for the mouse. He seemed not to comprehend just what was expected of him! This action kept up for a minute or two. R then tried the mirror with complete ritual. This brought no results. He came back to court R5 again. No results satisfactory to him. He now tried various inanimate objects in the vicinity. Next he went over the fence and approached nest 2-36 with ritual; he peered in all directions for a suitable candidate, wandering about a limited area. R5 (who could not see him) now rattle-bood loudly in the cage R came back over the fence and to the cage, keeping up his ritual for the mirror and for R5. No results, so back over the fence again. I now shut R5 in the inner cage, opening the door of the outside cage hoping Rhody would go into it, and then I would let him in with R5 with his mouse. As R5 now was quiet, I "rattle- bood", etc. from inside the cage. Rhody came back and walked about the roof of the cage. Discovering R5's presence in the upper annex, he pressed the mouse against the glass a foot from R5, who appeared but mildly interested. When R came down I tried to get him to come into the cage with me--a hopeless task. He now went down the lower driveway off to the west. In a few minutes I went down and found him at his post with the mouse, still looking for customers. I now returned and went to the Clearing. R was there. I invited him to follow me up the road, back to the cage, and he did, to my surprise. (Perhaps he was going there any- way). I let R5 out into the outer cage, shutting the outer door. Rhody immediately resumed his courting of R5 with full intensity. Response being unsatisfactory, he now headed for nest 2-36 for the third time. (Meanwhile R5 had cried when I talked to him). Rhody now went up into 2-36 with the mouse. After several minutes I followed. He was sitting in it, crying as I approached; the mouse was gone. R now worked at readjusting the fabric, still crying at intervals, once even with a twig in his bill with a quavering sound. He stayed in the nest for perhaps 5 minutes, then came down, composed and friendly, to sun his back in the lee of a low bank near the nest tree. I left him there. If and when it seems advisable to get Rhody and R5 together, procedure will be altered. It can be done by withholding the mouse from Rhody until he comes into the outer cage for it. I forgot to record that, when R approached R5 with the mouse, and was not performing his ritual, he made a series of low coot s and that R5 now has begun to ook--the "embarrassed" sound of Archie and Terry under similar conditions. I did not look up Rhody again until 11:25; now it is 12:20. Activities of Rhody, 11:25 to 12:15 (and R5) When I stepped out of the door at 11:25, a rattle-boo announced Rhody's return to the roof of the observatory. I went to the outer cage, joining R5 who was in there, without disturbing him. He was on his perch looking and listening for R. After a few minutes I koke, koked. Whether my technique is improving, or whether my calling had anything to do with it or not I do not know; but R soon appeared at the cage, taking station at the wire and "peek-a- booing" from either side of a low chamise at the cage corner, at R5--now on the ground by me sunning his back composedly. R5 re- fused to get excited, so R turned his back to the sun also. Soon he darted off along the fence to the east in one of his rattle-boo- ing circuses, thence over the fence to the next tree,
